Meningiomatous changes in the optic canan: a polytomographic study

C M Strother, W F Hoyt, R E Appen

    Radiology
    |April 1, 1980

    Summary

    Complex-motion tomography aids in diagnosing paracanalicular meningioma by revealing subtle optic canal bone changes. This imaging technique is superior to plain radiographs for detecting these tumors causing optic nerve compression.

    Area of Science:

    • Neurology
    • Radiology
    • Oncology

    Background:

    • Optic nerve compression can result from insidious tumors like paracanalicular meningioma.
    • Standard skull radiographs and non-tomographic views often fail to detect early bone changes associated with these tumors.

    Observation:

    • Eleven patients with unilateral optic nerve compression and normal initial radiographs were studied.
    • Paracanalicular meningioma was surgically confirmed in 10 of the 11 patients.
    • Complex-motion tomography was performed on all patients.

    Findings:

    • Complex-motion tomography revealed characteristic bone alterations in the optic canal in all cases.
    • Observed changes included canal enlargement, contour variations, and atypical cortical bone appearance.

  • Specific bone changes noted were diffuse spongy thickening, saw-tooth exostoses, and localized smooth bone thickening.

    • Implications:

    • Complex-motion tomography is a valuable diagnostic tool for paracanalicular meningioma, especially when initial imaging is inconclusive.
    • This technique offers superior diagnostic accuracy compared to angiography and pneumoencephalography for detecting subtle bone involvement.
    • Early and accurate diagnosis through advanced imaging can lead to timely surgical intervention and improved patient outcomes.
